Discover the versatility and reliability of SS400 steel, a widely used structural material known for its excellent strength, weldability, and affordability, making it ideal for construction, machinery, and industrial applications.
The most widely used steel SS400
1.SS400 is a type of SS material (Structural Steel) known as general structural rolled steel.
2.SS material is steel manufactured by rolling as a material for general structures. The name of SS material is represented by the symbol "SS" followed by a 3-digit number. It was previously marked as SS41. The 3-digit number represents the tensile strength of the material. If it is SS400, it means that the tensile strength is 400N/mm2 or more for structural steel.
3.In addition to SS400, there are SS300, SS490, and SS540 types of SS materials, but SS400 is the most widely used. SS400 is characterized by being inexpensive and easy to obtain compared to other metal materials. It is also easy to weld, cut, and other processes. It is also often circulated in the form of plates, and sheet metal processing, laser cutting, etc. can also be performed. However, quenching cannot be performed. In addition, because it is easy to rust, it needs to be rust-proofed by electroplating, black dyeing, etc.
4. In addition to being used as a structural material for bridges and ships, SS400 is also widely used in the mechanical field such as large machinery and vehicles to the construction field.

Advantages and Disadvantages of SS400
1. Advantages:
① Low price and easy to get
② Easy to weld
③ Suitable for sheet metal, cutting and other processing
④ High versatility
2. As a widely circulated general material, SS400 is cheap and easy to get compared with other metal materials. Compared with stainless steel, the material is soft, so it is also easy to process such as cutting and sheet metal processing, and can be used for various purposes. Since the carbon content is low and it is not easily affected by heat, it is also suitable for welding.
3. Disadvantages:

3. Disadvantages:
① Cannot be quenched
② The texture is relatively soft among iron and steel materials
③ It is easy to rust and requires anti-corrosion measures such as electroplating and painting
4. SS400 is a very common material, so it is not a particularly strong material as an iron and steel material. When a stronger material is required, it is necessary to study and select other materials. In addition, since its carbon content is low and it cannot be quenched, it is not possible to process the surface to obtain hardness only. It is also easy to rust, and needs electroplating, painting, and oxide film (black skin) protection.

Common surface treatments for SS400
1. SS400 is easy to rust, so it is often subjected to surface treatments such as nickel plating and chrome plating.
2. Common surface treatments:
2. Common surface treatments:
① Ferrous oxide film (dyed black)
② Electroless nickel plating
③ Hard chrome plating
④ Trivalent chromate
